Abstract:
An optical coupling module includes first, second, and third substrates, first and second optical fibers, and first and second lenses. The first substrate has a surface formed with a first V-groove. The second substrate has a surface formed with a second V-groove. The third substrate is arranged between the first and second substrates and has a surface formed with first and second recess. The first to third substrates have the surfaces flush with each other. The first and second optical fibers are fixed in the first and second grooves, respectively, and are arranged such that their end faces oppose each other. The first and second lenses are fixed in the first and second recesses, respectively, and are arranged on one optical axis of the first and second optical fibers to be spaced apart from each other by a predetermined distance.
Abstract:
An optical waveguide multiplexer for use in optical fiber amplifiers or the like, which is simple in configuration, permits manufacturing at high productivity, and is reduced in size and moreover susceptible to little insertion loss, is to be realized. A multiplexer-branching filter is provided with first to fourth input/output (I/O) terminals. Part of an optical signal emitted from the first I/O terminal is reflected by a branching film, formed over one face of a glass plate, and led to the second optical I/O terminal. The rest of the optical signal penetrates the glass plate, and further penetrates an optical multiplexing film, formed on the other face, to be led to the third optical I/O terminal. The invention has a particular characteristic that the thickness t of the substrate is set so as to satisfy the condition of t.gtoreq.w/cos.theta..times.tan[sin.sup.-1 {(sin.theta.)/n}] where n is the refractive index of the substrate; w, the beam diameter of the output light of the optical I/O terminal for multiplexing the signal light with an pomping light; and .theta., the angle of incidence from this terminal to the substrate. By setting the substrate thickness at or above the value stated above, the optical path of any leak light from the pomping light side is deviated from that toward the monitor side, and no pomping light can enter into the monitor. It is also possible, by adding an aperture film to the substrate, to further reduce the leak light.
Abstract:
An electric device has a casing with an air-inlet and an air-outlet, a main unit disposed inside the casing, a first temperature sensor for detecting the temperature inside the casing, a second temperature sensor for detecting the temperature outside the casing, an electric fan, and a control unit. The control unit rotates the electric fan at the time of the low-temperature startup such that the temperature detected by the first temperature sensor is lower than a preset first threshold value, while the temperature detected by the second temperature sensor is higher than the temperature detected by the first temperature sensor.
Abstract:
A server system is provided in which it is possible to avoid an improper operation or malicious operation on, for example, a power switch of a server. In such a system, both a management server and multiple servers are connected to a network. Each multiple server includes: an authentication key storing portion which stores an authentication key; and a management module which compares between data inputted by operating the operation switches and the authentication key stored in the authentication key storing portion, wherein the management module sets the operation switches available if the input data and the authentication key are the same. The management module includes a function of writing the authentication key received from the management server into the authentication key storing portion. The management server includes a virtualized environment software which transmits the authentication key to each of the multiple servers via the network.
Abstract:
An optical filter module with isolator function that has no polarization dependent property and in which no polarization mode dispersion occurs. An optical filter is arranged between a first optical input and output terminal and a second optical input and output terminal. A polarization splitting unit is arranged between the first optical input and output terminal and the optical filter, for separating the light into a first straight polarized light and a second straight polarized light which are in parallel to each other and which have polarization states perpendicular to each other. A first polarization rotation unit is arranged between the polarization splitting unit and the optical filter, for rotating the polarization state of the first straight polarized light by 90.degree. and then sending a first rotated light to the optical filter. A second polarization rotation unit is arranged between the optical filter and the second optical input and output terminal, for rotating light passing through the optical filter by 90.degree. and then sending a second rotated light. A polarization combining unit is arranged between the optical filter and the second optical input and output terminal, for combining the first rotated light with the second rotated light and outputting the resultant to the second input and output terminal.

The present invention can provide a polymer film having an Ra (arithmetic average roughness) of 0.5 μm to 2.5 μm, an Ry (maximum height) of 3 μm to 11 μm, an Rz (ten-point average height) of 3 μm to 8 μm, and a light transmittance of 85% or higher. A preferable embodiment of the present invention can provide, at the same time, an optical diffusion function, an improved luminance, a transmittance and the like which are of a sufficient level not realized conventionally. In a still preferable embodiment, Sm (average concave-concave/convex-convex interval) of 90 μm to 160 μm and the average inter-local peak interval (S) is 5 μm to 15 μm.

A cluster system of mutual standby type forms groups each composed of a job execution system and a job standby system for taking over the job when problems occur in the job execution system, and provides information processing devices each with a job execution system and a job standby system of different groups. The information processing devices each include: an upper limit value storage unit for storing a power upper limit value, a power control unit for controlling use of power by its own information processing device so as not to exceed the power upper limit value stored, and an upper limit value setting unit for causing the upper limit value storage unit to store a power upper limit value smaller than the maximum power consumption of its own information processing device when it is not necessary to take over the job of another information processing device.
Abstract:
A computer system comprises a computer that includes a plurality of CPU sockets including one or more CPU cores, a crossbar switch, and a memory controller each, and memories connected under the respective plurality of CPU sockets, the plurality of CPU sockets being connected to each other. When all the CPU cores in a CPU socket enter a power saving state and a total amount of memory use falls below a predetermined threshold, the computer relocates contents of the memory connected under the CPU socket to a memory under another CPU socket, thereby eliminating an access to the memory connected under the CPU socket and bringing a whole of the CPU socket into the power saving state.
